Queries :: Nested IIF - Returning Calculated Results In A Query
Oct 30, 2013
What is the best approach to returning calculated results in a query. I have been using nested IIf statements that include DateAdd but I think that I am at a point where there must be a better way.
I want my query to calculate a date based on:
1) A Type field from my table
2) A calculated date based on other query fields.
My query has the following fields:
[Type] [Action 1] [Projected Action 1] [Projected Action 1 Revised] [Action 2]
I want to create a calculated field for [Projected Action 2] that says:
If [Type] is "A" then
if [Action 2] Is NotNull, Null
if [Action 1] is NotNull, [Action 1] + 10 workdays
if [Projected Action 1 Revised] is NotNull, [Projected Action 1 Revised] + 10 workdays
if [Projected Action 1] is NotNull, [Projected Action 1] + 10 workdays
[Code] ....
I would like to keep using nested IIf but I keep running into problems and I thought that there is probably a better way.
I have a simple nested query that is not working as expected. My inner query returns 102 records but when I run with outer query I only get 96 records. Below is my query, I don't really want to pull the same fields from both tables but I was doing to test. The values that are missing are those that don't exist with the monthenddate 8/31/2014 - a left join should fix that but doesn't seem to be working ..
Code:
Select distinct a.entity, a.gl_account,a.profit_center,[Open Items_1].profit_center,[Open Items_1].gl_account,[Open Items_1].entity from( SELECT DISTINCT [Open Items].entity, [Open Items].gl_account, [Open Items].profit_center FROM [Open Items] )a left outer JOIN [Open Items] AS [Open Items_1] ON (a.profit_center = [Open Items_1].profit_center) AND (a.gl_account = [Open Items_1].gl_account) AND (a.entity = [Open Items_1].entity) Where ([Open Items_1].MonthEndDate=#8/31/2014#)
I have two tables Contacts & Allowance. There is a relationship defined between the two based on Contact ID (primary field/contacts - foreign key/allowance). The Contacts table has Firstname + Surname. I have produced a query based on certain fields in both tables however the result is totally pulling incorrect info.
I am building a prototype database and currently has two records in it (I know for certain they are not duplicates). Attached is the relationship and below is the query. The query keeps returning the correct results but twice. (Duplicate results.)
SELECT DISTINCT WeekdayName([Weekdaynumber],False,1) AS Weekday, [Master Data].Date, [Master Data].Machine, [Master Data].Shift, [Master Data Query].[Master Data_Product Code], [Master Data Query].[Cases/Pallet], [Master Data].[Expected Pallets to Produce], [Master Data].[Actual Pallets Produced], [Master Data].[Damage (Units)],
SELECT * FROM ((TBL_Properties INNER JOIN TBL_Property_Landlords ON TBL_Properties.Property_ID=TBL_Property_Landlords. Property_ID) INNER JOIN TBL_Landlords ON TBL_Property_Landlords.Landlord_ID=TBL_Landlords.L andlord_ID) INNER JOIN TBL_Agents ON TBL_Properties.Agent_ID=TBL_Agents.Agent_ID;
so far. But I need to join the results from another query which will be calculating SUM(Pay). Is it possible to INNER JOIN to a: (SELECT ....) nested query?
I have a query which pulls up results based on the value of a text box. All works well except one field has a DOB (date) and if I search say for " /1976" I get no results, however search /76 and all the people with that year of birth show then show up. The date is stored in the dd/mm/yyyy format.
I'm using the like [forms]![clients]![searchfield] in the criteria of the query to bring up results.
I have a switchboard which runs a google style search query to find people based on their first name, surname, date of birth or NI number on clicking the search button. It uses the following criteria in the query Like "*" & [Forms]![SearchF]![Firstname] & "*" for each of the above fields.
This works perfectly until someone inputs a record that doesn't have anything in one of the fields. ie, full name and DoB, but no NI number. When a record is entered in this way, the table stores the record but the search query cannot find it.
Multi search wont return results: Obviously I have my table and search form. But have hit a problem that is probably simple to overcome, but for the life of me I cant see it.
The small peice of code I have used = forms]![searchF]![name1] I have also tried Like"*" & forms]![searchF]![name1] & "*" still not working. The qurey accompanying form (searchF) works to displaying searchF form unpopulated which I believe is correct. I should at this stage be able to fill out the one table heading (name1) where the query should return a result in the (searchf) form but it does not return.
The tables, forms and quries, have all been saved and closed and re opened many times
The form (searchF) propeties have been checked and double checked. I have even built a test table but the same things happen as my main table.
I have a query with two table's in them. One is filled, the other is still empty. Both table's are related to each other with the field "document number".
This was working fine in access 2000, now in 2003 it returns zero results. I am starting to think it is because one table is empty it returns nothing. How can i adapt the query criteria or something else that it shows the results from table one, while table two can still be empty. One table holds the documents and all information about it, the other holds the information wich document is referenced on wich document. Now since i can have documens which don't reference to a document, i still want those in the list.
I have a table listing a number of cell phone products and their carrier along with their status' in the production process. I want the query to return the most recent status for each product for each carrier. However, out of the 20+ products that I'd like the most recent status for for each carrier, it's only returning about 12 products of the most recent status for one carrier.
Any help would be much appreciated! Leave a message if you need more clarification.
I'm having an issue with a query I created. When run the query requests an Artist Name. I enter this and it returns one result. However in actual table ther are two results for that artist. The only difference is that for the record that doesnt appear the field labelled "Gallery" has a zero value.
I have checked the table and the gallery field is not set to a required field so I dont understand why it wont show it as a result of the query.
running access 2000. I have a query that I selected to return the Top 1 record sorted descending on the date so it would pick the most recent entry. I did it by selecting Top 5 from the drop down box in query design mode and then changed the 5 to a 1 using SQL View from qry design.
SELECT TOP 1 Class.CourseID, User.UserName, Class.TrainerID, Class.ClassLocationID, Class.ElapsedTime, Class.ClassDate, Class.Comments FROM [User] INNER JOIN Class ON User.UserID = Class.UserID ORDER BY Class.ClassDate DESC;
It still gives me as many records as are entered on the system. How can I get JUST the most recent record entry?
I have a db with 2 tables, one containing basic info FirstName, Surname, YearGroup, and another table with other data. I imported a list of names into the first table, firstname and surname only were imported, other field was left empty, other table was also left empty. I made a simple select query to pull all records from both tables and i get no results at all. None of the imported names show on the query results. what I am missing?
SELECT CPL_CLIENTS.CODE, CPL_CLIENTS.FULLNAME FROM CPL_CLIENTS WHERE (((CPL_CLIENTS.FULLNAME) Like "*" & Forms!frmSafeKeep_AddClient_SearchDesig!txtSearchT ext & "*"));
As the control source of a listbox, so that the user can enter something in "txtSearchText", and the listbox will be narrowed to only those those clients that have a matching part of their name.
The problem is that the user enters, for example, "duncan", and the list returns nothing, when in actual fact there are 5 matching records. If the user enters "Duncan" (note the capital letter), they get all 5 records as they should.
If memory serves, access should only be case sensitive if you tell it to be - and this is working fine on other forms.
The only difference between them is the data source. Other forms are getting data from linked tables in the backend. This form is getting it from a linked Oracle table.
Hello all I was wondering if there is limitation to the number of IIf statements that can be nested in a calculated field. Basically I need to assign a particular ‘label code’ to a record that will be derived from data with in several fields within the query. The data from the table (that the query is derived from) will be completely deleted and recreated on occasions, meaning I can not write data back to the table as it would be lost when the re-creation happens. There is a possibility of many derivations for the ‘label code’ (maybe up to 100) so the nested IIf code will be substantial. If there is a better way to do what I want I am all ears however I am not a VB programmer so would rather stick to doing within the query design grid, or SQL at a stretch. Anyway the main focus to the question is there a limitation to the number of nested IIF statements.
I have done smoe baisc queries to sort, filter and report on data.How do I create a nested query where I don't repeat all the information across the query results line? Is there a way I can build a nested query to give all the SMCode codes associated with each appointment in one column separated by a coma?I have a table with appointments (APPTS):
RecID ADate ATime Durantion PVID Desc Case#
Then I have a table with Orders related to these appointments (ORDERS):
RecID Case# SMCode SMDate
Here's my query:
SELECT DISTINCTROW Appts.RecID, Appts.ADate, Appts.ATime, Appts.Durantion, Appts.PVID, Appts.Desc, Orders.SMCode FROM Appts INNER JOIN Orders ON Appts.[Case#] = Orders.[Case#];
I have different product groups and they can have one of 3 rental rates(5,4,3%) I have written a nested query but I keep getting parenthesis errors, the last one I got told me I must enclose iif functions in parentheses. I know its probably a small thing but I just cant see it. By the way the server is German so ; need to be used instead of ,.
IIf([view_India]![Sub_Group] In (1730;1810;2870);5;iif Left([view_India]![Sub_Group];2) In (01;02;21;24;29) ;5;iif([view_India]![Sub_Group] In (3310;3330;3340;3360);3;4))))
I'm trying to make a nested if then statement in a query field, and I can't figure out why I can't get my formula to work:
Volume: IIf([MethodCode]="K",[total]*12.54*0.026873,IIf([MethodCode]="S",([length]*[width]*[depth])/2,IIf([MethodCode]="M" And [Location]="SH",[total]*5.08*0.026873,IIf([MethodCode]="M" And [Location]="C",[total]*18.58*0.026873," "))))
I keep getting the "data type mismatch in criteria expression" error. If I separate out all the individual if then statements individually, they work. But if I connect them all as a nested if then it doesn't work.
Some essential background first. I have a Balances table which records balances by date. I also have an Issues table where problems are logged. There is a one-to-many relationship between Balances and Issues (i.e. each Balance can have multiple Issues). I also have a Comments table where updates for each Issue are recorded. There is again a one-to-many relationship between Issues and Comments (i.e. each Issue can have multiple Comments)
There are two key date fields in the Issues table :FlagDate (the date an Issue was flagged by a user for investigation)
ResolveDate (the date said investigation was brought to a conclusion)
There is also a date field in the Comments table :UpdatedWhen (the date any given comment was added)
So the basic flow is that an Issue gets flagged (FlagDate), then various comments are added (multiple UpdatedWhen's) and finally the Issue gets resolved (ResolveDate)
I need to incorporate a trend graph which will show the counts ofNew (i.e. new issues flagged as of each day) Cleared (i.e. issues resolved each day)
Updated (i.e. issues not yet resolved but updated each day)
Unchanged (i.e. issues not yet resolved and not updated each day)
Outstanding (i.e. all unresolved issues as of each day)
This is the SQL I've put together to get that table of information on which to base my chart :
Code: SELECT [tblBalances].[BalanceDate] AS AsOfDate, (SELECT COUNT([tblIssues].[IssueID]) FROM [tblIssues] WHERE [tblIssues].[Flag] = True AND [tblIssues].[FlagDate] = [tblBalances].[BalanceDate]) AS New,
[Code] .....
The subqueries for 'New', 'Cleared' and 'Outstanding' work perfectly; the resultant dataset gives me one record for each date in the Balance table and correctly counts the number of issues falling into each of those buckets.
The problem I have is with the 'Updated' bucket. If a flagged issue happens to be updated twice on the same day (which is perfectly acceptable), it counts this twice as well. I don't want this as I just want to know how many issues were updated on any given day - not how many updates there were.
I tried using COUNT(DISTINCT) in the 'Updated' subquery but it gives me a syntax error - on further research, I don't think it's possible to use the DISTINCT keyword in a COUNT subquery (at least not easily)
I also tried grouping by IssueID within that 'Updated' subquery but it still gives me the duplicate count within the same IssueID (and returns nulls rather than zeroes for those days where no updates occured)
I think I need to add a subquery within the subquery () to only return the latest comment as of the date in question - something along the lines of :
Code: (SELECT TOP 1 [tblComments].[UpdatedWhen] FROM [tblComments] WHERE [tblComments].[IssueID] = [tblIssues].[IssueID] AND DateValue([tblComments].[UpdatedWhen]) <= [tblBalances].[BalanceDate] ORDER BY [tblComments].[UpdatedWhen] DESC) AS UpdatedWhen
But how to do this, nor if it is even feasible in Access to begin with.
Item: Access app front end for an SQL database (production tracking/job logging utility)
Problem: The app has a main search page that allows job entries to be located and opened by varies criteria (job#, job name, etc). I can currently run multiple searches on different criteria successfully but if I open a job window(which has been returned as result of my search) and then close that job window to do a new search my search function will no longer return any results(other then “Calculating….”) unless I close out the access app and reload.
Thanks in advance for any ideas that can point me in the right direction to hunt down my bug.
I have built a Project/Resource database for our department, and I am having an issue with 3 computers in the group. First, all of our computers are setup the same (as far as I can tell), however, there are 3 users that have the same issue...when selecting an item from a dropdown, it should populate the dropdown below it with a new list, based on the first dropdown. It is only on certain forms, and only happens on these three computers. If the users log into any other computers, it works fine. I know it's not alot to go on, but does this sound familiar to anyone? I'm at a complete loss!
When I run this query, it shows that 41 records are going to be appended. I click on yes, but when I go into the table to view the appended records they do not show.
Code: Public Sub test() Dim frm As Form Set frm = Forms!StationLevelSummary
[code]...
At the bottom im printing the content of the controls which are on my form. These should return 1 number, but for some reason it does not. Ive used this code many times but I cant figure out why nothing is being returned.
I'm trying to do a string compare between two variables. One string variable is part of an array (which I'm looping through), the other is passed to the function as an argument.the function should return the position of a field in the OrderBy string of a subform.Here's the VBA :
Code:
Private Function SortPosition(strOrderBy As String, strField As String) As StringDim arrSortedFields() As String Dim i As Long If Len(strOrderBy) > 0 And InStr(strOrderBy, strField) > 0 Then arrSortedFields = Split(strOrderBy, ",")
[code]....
The weird thing is, the line in blue returns True when, by watching the variables, it appears that it should not, and returns False when it appears that it should?
I would have thought the expression "[RandomField]" Like "[RandomField]*" should return True?And similarly the expression "[SomeFieldName]" Like "[ADifferentField]*" should return False?Have been using 'Like' for donkey's years and never seen it throw results like this before?
(P.S. The reason I need to use 'Like' rather than a straight = is to account for the possibility that a field may be sorted descending, and therefore to nullify the DESC keyword which may follow any given field...)
